In this study,the activated carbon fiber was modified with Na OH solution and used to removal Cd~(2+) ions in water by electrosorption. The results showed that the highest Cd~(2+) removal ratio was obtained by the activated carbon fiber modified with 2 mol / L Na OH solution. Thus,the influences of potential,temperature,and Cd~(2+) initial concentration on the removal ratio of Cd~(2+) were investigated with the modified activated carbon fiber by 2 mol / L Na OH solution. The results showed that the higher p...
